Answer:
95% Confidence interval: (14.4537 ,15.1463)
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 15 feet
Sample mean, = 14.8 feet
Sample size, n = 16
Alpha, α = 0.05
Sample standard deviation, σ = 0.65 feet
Degree of freedom = n - 1 = 15
95% Confidence interval:
Putting the values, we get,
is the required confidence interval for the true mean length of rods.
Answer:
67.3°C
Step-by-step explanation:
A = 25, T(0) = 100, T(1) = 90, find T(4)
dT/dt = -k(T - A)
d(T - A)/dt = -k(T - A)
d(T - A)/(T - A) = -k dt
ln(T - A) = lnC - kt
Answer:
99% confidence interval for the soil water content is determined by
(0.19474, 0.26926)
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given mean of the sample = 23.2% = 0.232
Given standard deviation of the sample = 1.0% =0.01
Given sample size 'n' =4
Degrees of freedom = n-1 =4-1 =3
critical value = 0.01
99% confidence interval for the soil water content is determined by
( 0.232 -0.03726 , 0.232 +0.03726)
(0.19474, 0.26926)
<u><em>Final answer:</em></u>-
99% confidence interval for the soil water content is determined by
(0.19474, 0.26926)
Answer:
line D i think
Step-by-step explanation:
line a and c have a positive slope. and line b has a way negative slope.
<span>The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .</span>
